DFIT Interpretation Course, SAGA Wisdom

This course covers the DFIT interpretation procedure from the paper URTeC-2019-123. The procedure was developed as part of a collaborative industry study sponsored by a group of six operators and one service company. It is the latest course offered by SAGA Wisdom,available to SAGA Wisdom subscribers.

Adding a fourth dimension: Optimizing for heat recovery

ResFrac lends itself particularly well to the optimization of hydraulically stimulated geothermal wells. ResFrac not only computes fracturing and reservoir flow simultaneously, but also calculates thermal stress changes and supercritical fluid properties. Fowler and McClure (2021) evaluate three geothermal designs: a closed-loop, a closed-loop with thermally conductive fractures, and an open-loop multi-lateral.

Modeling unlocked 60% improvement in NPV

HFTS 2 is one of the highly measured hydraulic fracturing pads in the world. In 2021, the HFTS 2 consortia and ResFrac collaborated on a modeling study to incorporate all the advanced diagnostics in HFTS 2 into a single, comprehensive model. This model was then employed in an automated optimization workflow to assess opportunities to improve NPV by adjusting well spacing, proppant loading, fluid loading, cluster spacing, and landing zone. Pudugramam et al. presented the ResFrac model calibration and optimization in URTeC 3723620 in 2022, showing a 60% possible improvement in NPV by optimization of well placement and completion design.

Devon and ResFrac model parent-child interactions in the STACK

Parent-child interactions have been a continual challenge for the unconventional oil and gas industry in recent years. At HFTC 2022, Devon and ResFrac co-authored a study on modeling parent-child interactions in the STACK in Oklahoma (SPE 209152). The parent well, two generations of children wells, and a remediation treatment in the parent well are modeled in a single, continuous ResFrac model. The continuous nature of the ResFrac modeling allowed for fluid exchanges between parent and children wells to be captured, while also requiring a holistic explanation for performance degradation in parent well post-hit. The model quantitatively described all historical observations (including damage to parent and subsequent recovery after remediation treatments) and is now suited for optimization of child well design and parent remediation programs.

Office hours recordings

Complex Econonomic Optimization, Part 1

For Office Hours this month, we had a presentation from ResFrac Director of User Success, Dave Ratcliff. He presented a Complex Economic Optimization workflow where he explains how to vary stage length, cluster count, and well spacing while keeping the perforation friction drop constant to maximize NPV/Section. This is part 1 of a 2-part series, we will continue the discussion in an upcoming Office Hours.

Modeling CO2 injection and long-term storage using ResFrac

For this month’s Office Hours, we had a presentation from ResFrac Senior Reservoir and Completions Engineer, Ankush Singh, on modeling CO2 injection and long-term storage using ResFrac. The true injection capacity of a CO 2 storage site should be calculated in terms of how much fluid can be injected economically, while minimizing the risks such as caprock failure and induced seismicity. We will discuss some of the fully coupled 3DResFrac simulations we performed to better understand the changes in the subsurface resulting from CO2 injection. The simulations demonstrate the importance of utilizing a fully integrated 3D hydraulic fracture, geomechanics and compositional fluid flow simulator to understand the subsurface risks and optimize CO 2 injection.
